Biography
Ivan Pavlov was born in Ryazan, Russian Empire in 1849, and he was known to be a curious child. He originally studied to join the clergy, but he later decided to dedicate his life to science, and he enrolled in the physics and mathematics department at the University of Saint Petersburg in 1870 to study natural science. In 1904, he became one of the fathers of classical conditioning through his study of dogs' salivary glands, teaching them to anticipate food at the sound of a bell, and therefore to salivate. That same year, he was awarded a Nobel Prize for Physiology or Medicine, and he died in Leningrad in 1936.
